Don’t settle for this OP! I’m older than you and 15 years into a pretty pointless marriage. I honestly don’t know why I’ve put up with being in a sexless marriage. If I could turn back time, I would. And I know that would mean not having my beautiful DC.
Our sex life was fabulous for about 5 years, then it dwindled and it became me initiating always and him mostly turning me down. That was really hurtful to be honest. We were then down to a couple of times a month for about 5 years. By some miracle I got pregnant 3 times (twice on first time trying and then one surprise when we had sex once in 18 months!!).
Our DC are wonderful. If it weren’t for them, I would have wandered away by now.
I used to feel very attractive. Now I feel invisible to my DH. He is like a brother. A very irritating brother. The idea of having sex with him now makes me feel a bit ick. It would be weird and inappropriate. We’ve crossed over a barrier of platonic relationship. Bizarrely he still likes a cuddle and peck on the lips every day, he buys me lovely thoughtful gifts and writes romantic messages in birthday/Valentines cards etc. I really couldn’t care less about these things.
Don’t be like me. Please listen to yourself (and all the advice on here) and move on.
I recently asked my DH if he watched porn (he avoided answering) and then I asked him if he is gay (he got offended by that). So in summary, I give up on finding out why he’s like this. It isn’t healthy and it isn’t fair.
We’re fortunate enough that we can buy a weekend home shortly. And my (secret) plan is to live mostly there alone when I retire in 15 years or so. DH can stay in our main house full-time and I’ll come back to stay for Easter and Christmas etc, basically when our DC visit us. Hopefully I’ll have a handsome younger gardener to peek my interest then lol. I live in hope that one day I’ll feel attractive and vibrant and desired again.
